What States Does the New Madrid Fault Run Through?

By Anna Duncan

The New Madrid fault is one of the most significant seismic zones in North America. Located in the central United States, it is responsible for some of the most powerful earthquakes ever recorded in the country.

But what states does the New Madrid fault run through? Let’s take a closer look.

The Location of the New Madrid Fault

The New Madrid fault runs through several states in the central United States. The fault zone stretches from northeastern Arkansas to southern Illinois and includes parts of Missouri, Tennessee, and Kentucky.

Arkansas

In Arkansas, the New Madrid fault runs through the northeastern part of the state. This area includes cities such as Jonesboro and Blytheville.

Missouri

Missouri is perhaps the state most commonly associated with the New Madrid fault. The seismic zone runs through southeastern Missouri, including cities such as Cape Girardeau and Sikeston. The infamous 1811-1812 earthquakes that shook the region occurred primarily in Missouri.

Tennessee

In Tennessee, the New Madrid fault runs through western parts of the state. Cities such as Memphis and Dyersburg are located within this area.

Kentucky

Finally, in Kentucky, the New Madrid fault runs through a small portion of western Kentucky near its border with Missouri and Tennessee. Cities such as Paducah are located within this area.

Conclusion

In summary, the New Madrid fault runs primarily through four states: Arkansas, Missouri, Tennessee, and Kentucky. While seismic activity has been relatively quiet in recent years along this fault line, it remains an important area for study and preparedness due to its potential for major earthquakes. Knowing which states are affected by this seismic zone is important for those living or traveling to these areas to be aware of their surroundings and stay prepared for potential seismic activity.
